6.1. POSITION "VOLTAGE"
This function permits you to display in real time the RMS value of AC/DC voltage, the peak
and Thd value of the 3 phase voltages (see paragraph 16.2), the waveform and the
harmonic spectrum of the 3 phase voltages.
6.1.1. Symbols
The VOLTAGE position has three working modes:
 METER
 WAVE
 HARM
These modes will be described in detail in the next paragraphs.
The symbols used are described below:
Symbol Description
V1, V2, V3 RMS value of the voltage of phase 1, phase 2, phase 3 respectively
V12, V23 or V32,
V31 RMS Value of the phase to phase voltages
Vpk1, Vpk2, Vpk3,
Vpk12, Vpk32 Peak value of the voltage of phase 1, phase 2, phase 3 and of the phase to phase
voltage 12 and 32 respectively
h01 - h49 Harmonic 01 - Harmonic 49.
ThdV Factor of total harmonic distortion of the voltage (see paragraph 16.2).
